Allow the user to scale shadow-map resolution per-light. Adapt the PCF scale based on shadow-map to pixel footprint ratio, since we can no longer assume that higher LODs don't need filtering. This allows using much lower shadow resolutions, which can yield quite significant performance improvements, with relatively little perceptual quality loss (at the cost of softening shadow edges). The per-light resolution scale is a literal scale, so for example 0.5 means half the resolution. The Scene Simplify Shadows setting has been updated to match this behavior.
